SOLDIER-CARRYING CAN-GAP.

Specification of Letters Patent.

Patented Dec. 29, 1908.

Application filed May 25, 1907. Serial No. 375,578.

To all whom it may concern: v

Be it known that I, JOHN J. RIonY, a citizen of the United States ofAmerica, and a. resident of New York citv, borough of Brooklyn, countyof Kings, and State of New York. have invented certain new and usefulImprovements in Solder- Carrying Can-Caps, of which the following is aspecification.

.The present invention relates to soldercarr ing can caps, such as areused to close the filling hole of fruit and other cans. Caps of thischaracter-are provided with a body of solder on the lower edge of theirdependent flange, and, after the cap is placed in posii tion on the can,asoldering iron is applied thereby fusing the solder and sealing the capto the can.

llcretofore it has been customary vide the lower edge of the flange withof solder both on its exterior and interior, the result of which is thatthe cap cannot fit snuglyagain t its adjacent shoulder on the can, andfurther, when the solder fused, it will have a tendency to flow upwardon the inside of the dependent flange and into the interior of the can.

The object of the present invention is to obviate this condition and toprevent the solder from flowing into the interior of the can. i

To this end the invention embraces the features hereinafter set forth.

In the accompanying drawings, the invention is embodied in a concreteand preferred form, but changes of construction can of course be madewithout departing from the legitimate and intended scope of theinvention.

In the said drawings :-Figures l, 2, 3 and a are. vertical sectionalviews showing the develo nnent of the blank, embodying" the invention.Fig. is a vertical sectional view of a portion of the can with the capin position.

Similar characters of reference indicate corresponding parts in theseveral views.

1 indicates a caphaving the dependentflange 2 provided with thesupporting shoulder 3 at its lower end on the exterior of the flange.

In Fig. 1 the blank is shown as it appears after beingcut and drawn up.The blankis then subjected to the action of a suitable die to proa body4 down over the solder which forms it with a bead at on the upperi I endof the flange and on theexterior thereof,

.This is shown in Fig. 2.

As shown in Fig. 3the blank is now suloQ jected to the action of a diewhich will turn up the supporting shoulder-3. A bodvof solder 5 is nowplaced on the supporting shoulder and the cap is again subjected to theaction of a die which will flatten the bead so as to hold the same inposition. This is shown in Fig. 4,

In Fig. 5 the cap is shown in position on the can in the groovesurrounding the aperture or filling hole 11. It will be noticed that theinterior surface 7 of the dependent flange abuts against the inner wall8 of the groove 10, and that the projecting supporting shoulder 3 abutsthe outer wall 9. Since however, the shoulder 3 is of less depth thanthe wall 9, the solder when fused covers the shoulder 3 completely andforms an exterior seal between the dependent flange of the cap and theouter wall of the groove.

What is claimed is 1. The combination with a can having an aperturesurrounded by a groove, of a soldercarrying can cap having a dependentflange and an upwardly extending shoulder, supporting a body of solder,both fitting into and abutting respectively against the inner and outerwalls of the groove, the said supporting shoulder being of less depththan the abutting outer wall of the groove, where: by the solder, whenfused, will cover the supporting shoulder and form an exterior sealbetween the outer Wall of the groove and the dependent flange of thecap.

2. A can cap having a dependent flange. a projecting supportin shoulderat the lower end of said flange, :1 body' of solder resting on the saidsupporting shoulder, and a bead on the cap for holding the solder on thesupporting shoulder.

3. A can cap having a dependent flange,

a projecting supporting shoulder at the lower: end of said flange,'abody of solder resting on said supporting shoulder, and a downwardlyprojecting bead extending from the upper end of the cap for holding thesolder on the supporting shoulder.

4. A-can cap, having a dependent flange provided with a supportingshoulder at its lower end and a head at its upper end on its exteriorsurface. and a body of solder confined between the supporting shoulderand bead.

5. A can cap having a dependent flange,"

an upwardly proj'ectin supportin shoulder at the lower end of saidflange, b y of solder resting on the saidsupport-in shoulder, and a beadon the cap for holding the solder on the supporting shoulder.

.6. A can cap having a dependent flan e, an upwardly projectingsupporting shoul er at the lower end of said flange, a body of solderresting on said supporting shoulder, and a downwardly projectlng beadextending from the upper end of the cap for holding the solder on thesupporting shoulder.
